摘要: This paper presents performance results of three high-resolution parameters estimation algorithms: ESPRIT, SAGE and RiMAX. MIMO indoor radio channels which include measurement-based time-delay diffuse multipath scattering (DMC) were emulated to evaluate the both algorithms. The impact DMC on parameter accuracy is studied by adjusting its power with respect specular component. For all discussed scenarios, it clearly demonstrated that RiMAX outperforms ESPRIT do not into their data model. preliminary highlight importance necessity account for presence in models accurately estimate channel parameters. Otherwise, very poor estimates coherent component are expected would turn result wronged propagation prediction models.
